9004 High-Wattage bulbs

Thanks all for the valuable input concerning the high-watt bulbs. I had the
feeling that something was too good to be true. Maybe another set of Hella
is what I need. How do Rally drivers wire up that brace of lights?
Many relays and many fuses? Does anyone know where I can get a light bar
like that?(3 lights each side)
